Application filed August 21, 1914. Serial No. 857,823.

1 '0 all whom it may concern Be it known that I, HENRY A. Honsn, Jr, a citizen of the United States, residing at Long Hill,in the county of Fairfield and State of Connecticut have invented certain.

new and useful Improvements in Locking Devices for Hubs; and I hereby declare the following to be a full, clear, and exact de scription of my invention, such as will epablc others skilled in the art to which/1t appertains to make and use the same.

Reference is had to the accompanying drawings and to figures of reference-marked thereon, which form part of this specification.

Like figures of reference refer to like parts.

This invention relates to ratchet devices for securing nuts to hubs of demountable vehicle wheels, and is particularly adapted for large wheels.

One feature of the invention is the releasingmeans which is brought into action when a wrench is put upon the nut for turning the same.

The hub of of two parts,

a demountable wheel is made the inner one of which is journaled on the axle or shaft, or it may be fixed thereon. The outer hubpart is fixed to the spokes and rim and is therefore removable with the wheel. in use for locking the hub parts together against turning on one another and a single nut, in threaded engagement with one of the hub parts, is used to secure the said parts longitudinally. This nut is in threaded engagement with the inner hub part andhlconcentrically engages the outer of the said parts.

One of the objects of this invention is to provide a device that will fix the hut against unscrewing, and to automatically release the device,-when applying a wrench to turn thenut.

A further object is to make the said device operative within the small space available between the nut and the outer hub part, and also to have the co-acting parts 01" the device separable, yet attached respectively to the nut and one of the hub parts, when the wheel is taken off.

A further object is to have the parts of said device so related in their co-action that they will follow each gagement during any other in locked eneccentric movement the nut and the outer hub Various means are of the nut relative to kind of floating, movement, while unscrewing from yet anchored or securing the nut against the inner hub part.

Inasmuch as the hub parts, when together, are secured against turning on one another, by pins or lock the parts, and it will be retained against unscrewing from the inner hub part.

For purposes of convenience and accessibility, I have made the parts of. the ratchet device attached to and co-acting between part. I provide a series of peripheral teeth adjacent to the nut, and have a pawl or tongued) lever positioned for reciprocation in the nut. The pawl or tongued lever is spring pressed outward for engagement with the said teeth- The peripheral teeth may be either on a ring which engages a stud on the outer hub part, or they may be formed upon the end inturned edge of the outer hub part.

The details of construction of this invention are illustrated in are hereinafter is explained and what 1 claim is set forthl In the drawings: Figure l is a sectional side elevation of the hub parts and nut having the said ratchet. device incorporated therewith. Fig. 2 is a sectional front elevation of that which is shown in Fig. 1. Fig. 3 is a perspective view of the conical nut showing the tongued lever or pawl incorporated therewith. Fig. 4 is a perspective view of the tongued lever. Fig. 5 is an elevation of thv toothedsplit ring. Fig. 6 is a sectional side elevation of hub parts aving incorporated therewith a modified form of the said ratchet device. Fig. 7 is a sectional front elevation or that which is shown in Fig. 6. Fig. 8 is a perspective sectional view of the t and 8 and illustrates the manner in which a wrench, when applied to the nut, epresses the spring pressed pawl to free it from engagement with the teeth. I

In Fig. 1, 1 is the shaft upon which is positioned the inner hub part 2. 8 is the outer hub part, having an inwardly curved end 4:, forming an annular space 5, with the conical nut 6. which is in threaded engage ment at 7, with the inner hub part 2. 2 are studs fixed upon the flange 2", of the inner lJ I) part 2, and are in engagement with holding the drawings, and, described, their operation" the hub parts, in a other means, we may nut upon the outer of said hub nut shown"in Figs. 7 I

.5 of the pin 11*.

60. toothed as 'shown in Fig. 7.

with the end 4 of the outer hub part 3. -9

5 is a. toothed ring which is split, so that its free ends (not shown in this figure) are in engagement with the stud 8, to prevent the ring 9' from turning within the end 4 of the outer hub part 3. 10 is the tongued lever pivoted at 11 to the nut. 63. Upon the tongued lever 10 is the finger 12 which engages a shoulder 13 formed within the nut (3, to limit the outward movement of the tongued lever 10, due to the compression springs 14 and 15. 16 is a plate upon the nut 6, which extends over the recess 17, oo-

cupied by the finger 12.

In Fig. 2, is shown the beveled tongue '10 in engagement with one of the teeth 9 of the ring 9. In this figure are shown the ends 9" and 9 01'' the ring 9 positioned for engagement with the stud 8.

In Fig. 3, the tongued lever 10 is shown pivoted to the hexagonal head 6 by means The beveled tongue 10 is shown projecting above the peripherial surface 6* of the nut 6. A beveled part 10 of the tongued lever 10, is shown to project above the flat .surfaceG of the head 6.

o In Fig. 1, is shown the position of the springs 14 and which project from pocketed holes in the body of the tongue'd lever 10' and also is shown the relative positions of the beveled tongue 10 and the asifing'er 12.

linFig. 5, is shown the split ring 9 having internal teeth 9- In Fig. 6, 18 is the inner hub part. 19 is the outer hub part, having" an inwardly in curved end 20, and a. conical part 21, which is in engagement withlthe conical end of the nut 22. The nut 22 is in threaded engagement at 23, with the inner hub part 18 are studs fixed upon the flange 18 of as the inner hub part 18, and are in engagement with the holes in the flange 19 of the outer hub part 19, to prevent the hub parts 18 and 19 from turning on one another. T 1e edge of the inner curved end*20 is Adapted for engagement with the teeth is the tongued lever or pawl 22% pivoted within the slot on the nut 22 at the pin 24. The spring coil 25 passes through a hole 27 in the pawl 22 t5 to engage the pawl to govern its outward movement, between the teeth in the end 20.

In Fig. 7, teeth marked 28, are shown cut in-the end 20 'of the outer hub part 19. The springcoil 25 is shown to fit against the to inner curved surface of the nut 22 until it is within the vicinity of pawl 22. The portion 25 of the spring coil 25 is straight so that its end 25 and the shoulder 25, form a stop to limit the outward movement of the pawl e5. 22. l The lower end of the spring coil 25 is bent outward to engage a hole at 29 in the nut 22.

In Fig. 8, the nut 22 is shown in section, and illustrates how the beveled surface 26 of the pawl 22*, is depressed by engagement with the wrench 30,'whercby the tongue 31, of the pawl or tongued lever 22, is submerged below the periphery of the nut 22, at the point 32. A portion of the spring coil 25, engages a hole in the pawl 22, at 27, as is clearly shown, the pawl. 22 being pivoted .on the pin 24.

In operation, referring to Fig. 2, if the nut 6 is turned clockwise, the beveled tongue 10 will pass consecutively over the teeth 2) and coming to rest in some such position as that shown, will be prevented from'turning backward by means of the engagement. of the radial surface of the tongue 10, with one of the teeth 9 adjacent thereto. The engagement of the tongued lever 10, to the ring 9, in the act of preventing the back turning of the nut i will cause the ring end 9to press against the stud 8. The illustration shows thb device adapted for right threaded nut. For a left threaded nut, the only change necessary is to reverse the bevel on the tongue 10.

\Vhen it is desired to unscrew the nut (3, a wrench adapted to lit the head (3 is pressed into engagement. therewith and depresses the beveled part-oi 10" of the lever 10, thereby causing the tongue 10" to be thrown out of engagement with the teeth 9 of the ring 9. When the wrench is removed, the springs 1 and 15 shown in Figs. 1 and 4;. act to throw out the tongue 10 to engage the teeth 9 and prevent the reverse turning of the nut 6. Any eccentric movement of the nut (3, will not disturb the engagement of the tongue l0 with the teeth 9 on account of the strong action of the tongued lever 10, to cause the tongue 10 to follow the teeth 9.

When the wrench 30, shown in Fig. 3. is applied to the nut 2 the nut 22 being in place as shown in Figs. (3 and 7, the pawl 22 will be out of ehgagement with the teeth 28, and the nut (an be turned in either direction, as explained above with reference to the lever 10.

The modified form of my device shown in Figs. 3, 7 and 8, dispenses with the iiug shown in Fig. 5, yet the pawl 22 has a beveled surface 26 adapted for the same purposes as the beveled surface 10" shown in Fig. i.

The construction of the device herein shown may be modified yet not depart from the spirit of my invention.
